Abstract

The invention relates to a power cut protection device of a solar automatic tracing system, comprising electrical source (1), an electricity grid testing circuit (2), standby electrical source (3), a relay (4), an automatic tracing controller (5) and an electrical motor execution system (6). The input terminal of the electricity grid testing circuit (2) is connected with the electrical grid, the output terminal is connected with the I/O port of the automatic tracing controller (5); the input port of the standby electrical source (3) is connected with the electrical grid, the output terminal is connected with the relay (4), the relay (4) is connected with the power supply terminal of the automatic tracing controller (5), and the automatic tracing controller (5) is connected with the electrical motor execution system (6). The invention can detect the electrical source of the tracing system in real time and transfer the state of the electrical source to the automatic tracing controller (5). When the tracing system works normally, power is directly supplied to a gearing of the tracing system by the electrical source; when power cut happens to the electrical source, the standby electrical power supplies power to the gearing of the tracing system and executes the reset program of the tracing system, thus facilitating the solar tracing system to be in safe pose.

Description

technical field [0001] The invention relates to an automatic sun tracking system, in particular to a power failure protection device for an automatic sun tracking system. Background technique [0002] With the increasingly prominent energy and environmental issues, the development and utilization of renewable energy has gradually attracted the attention of the world. Solar energy has become a fast-growing renewable energy due to its cleanness, wide distribution range, and convenient utilization. Solar photovoltaic power generation is one of the main forms of solar energy utilization, but due to the high price of solar panels, the cost of photovoltaic power generation remains high, thus restricting the development of solar photovoltaic power generation industry. Therefore, how to improve the utilization efficiency of solar energy and reduce the cost of solar energy utilization has become a hot spot of people's research at present. Tracking the sun, ensuring that the inciden...
